Application led October 6,

To all whom it may concern.' f

Be it known that I, NOAH B. CANNADY, a citizen of the United States,'residing at Eureka, in the county of Greenwood and State of Kansas, have invented a -new and useful Weather Strip, of which the following is a specification.

This invention has reference to weather strips, and more particularly to sectional metallic weather strips wherein one section may move within the opposed section to provide a fluid-tight connection ktherebebetween.

The primary object of the invention is to provide a metallic weather strip constructed in a manner to exclude moisture and air, the weather strip embodying opposed elements adapted to be moved into close engagement.

Another object of the invention is to pro-k vide a weather strip of this character which may be readily and easily applied to` a sash, it being necessary to'make only minor changes in the sash construction to install a strip.

With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings Figure 1 is a vertical sectional view through a sash and its frame, the same being supplied with a weather strip constructed in accordance with the present invention. y

Figure 2 is a sectional view taken on line 2 2 of Figure 1.

Figure 3 is taken on line 3-3 of Figurel.

Referring to the drawings in detail, the frame is indicated generally by the reference character 5, and is shown as formed with the usual guide strips 6 and 7, there being provided a central guide strip 8 disposed between the sash members, tohold the same in spaced relation with each other.

The frame also includes a sill 9 to which is secured a metallic plate 10 that has an upward extending flange 1l terminating in a spaced downward extension 12,.,the space r-betiveenthe body of'thejflangeanddownward extension' being designed Lto f 'accomf f modate the vupwardlyextending 'right an- ,i Y

` gled portion l13 of the plate'lll which isi secured to the sill as by'means'- of lthe screws 15. These plates 10 and 14 .extend across the entire width of the lframe to guard the y window throughout its entire width. j

Carried by the lower sash which is indi-` i cated by the reference character 16 and. disposed adjacent tothe outer sidethereof is a transversely extending platel 1oA which is designed Ito move over the downward ex. 7

tension l2 of the flange 11 'forcing the down ward extension into vclose engagement with the portion 13 of the plate 111, thereby in' suring an air-tight connectionbetween the "1 elements of the weather strip. It might,A be

further stated that the lower rail'of lthe. y

sash 16 is cut away as at 17 to"'provide` a clearance for the, upwardly extending elements ofthe weather strip.

As clearly shown by Figure l of the drawings, the upper rail of the lower sash is.in.`

clined as at 18 to (cooperate with ther inf clined surface 19 of thelower rail of the upper sash 20, the lower'railsupporting a transversely extending flanged plate 21 formed of iexible metal, a portion of the plate being turned downwardlyto lcontact with the inclined, edge 18 of the lower sash,

and insure a fluid-tight connect-ion'betwee'n" thel adjacent edges of them-,upper and'lower sashes. 4 'l y 'The upper sash also embodies an upper i rail 22 to which is secured a flexible ymetallic plate 23 formed with a downwardly extending portion 24 that contacts withthe downwardly extending iiange 25 formedon vthe plate 26', the latter plate bein'gcarried by the window frame. Thus'it will be vseen that since these contacting plates are formed l, of flexible metal, a binding action will be set i up therebetween lto insurean air-tight con'- nection.

In order that an airtight connection may be provided between the sashes vand the side l bars of the casing orwindow 4frame', plates.l

27 are provided, the lsame being'secured to portions29 that move between the opposed the sashes as vby means of the screws 28.41075"k These plates are formed with right angled the frame as clearly shown in Figure 2 of the drawings.

Vhile I have shown and described la construction `for providing an air-tight connection between the side rails of the sashes at one side and the frame in which the same move, it is to he understood that this construction is duplicated with both sashes.

Havinof thus described the invention, what is laimed as new is v:- p

In a window construction comprising a sill, and a sash having a rahbeted lower rail,

a .platesecured `to said sill and having an upwardly extending flange 'formed integral I therewith, a plate secured to said sill cooperating with Ethe rst mentioned plate and having an upwardly extended [iange terminating in a downwardly extended portion disposed in spaced relation therewith to provide a pocket for the first mentioned flange and a plate secured to said sash rail rail and cooperating with said rabhet to form a channel, said Hanges adapted to he received in said channel and trictionally engage the walls thereof.

In testimony that l claim the foregoing as my own, I have hereto afxed my signature in the presence of two witnesses.
